GANG-PLOW.

Specification of Letters Patent,

Application led1une 7, 1912. Serial No. 702,300.

To all whom t mag/"concern f v B e it known that I, ARTHUR G. BUGLER, a citlzen of the UnitedStates, residing at arner, in the Province of Alberta and Do minion of Canada, have invented new and useful Improvements -in Gang- Plows, of -Whichthe following is a' specification.

This invention relates to gang plows, and it has vfor its object to produce a gang plow of simple and ehcient lconstruction in" which the individual plows shall be equipped with gage wheels whereby the action of each plow may befcontroll'ed. i

A 4further object ofthe invention is to pro-4 vide simple and improved means for connecting the indivi-dual plow beams with the traction frame in such amanner thatfthe front end oi each bea-m may be minutely adjusted both vertically and laterally. t

A further object of the invention-is to proy vide springs engaging the plow beams,

whereby said beams will be yieldabl'y supportedv in such a manner that ifa plow should deviate from its course, owing to obstructions in the path thereof, itwill be quickly and surely returned to its proper place as soon as the obstruction has been I passed.

With these andother ends in View which will readily appear as the nature of the invention is better understood', the same conl sists inI the improved construction and novel arrangement and combination of parts which will be hereinafter' fully described and particularly pointed out in the claims.

, In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation isV necessarily made to the precise structuraldetails therein exhibited, but that changes, alterations and modifications within the scope of the claims-may be resorted to when desired.

In the drawings,-Figu-re 1 is a top plan View of a gang plowconstructed'inaccordance with the invention. Fig. 2 is a side elevatioxr, showing one-of the .plows and showing also, insection', the beam of a traction frame with whichv it is connected. Fig. -3 isfa side viewshowing the opposite side' of the plow.- F ig. 4 is a tope plan-vlew, enlarged,

showing a portion of the rear beamo the..

traction frame and the .front endl of the-plow beaml connected therewith. Fig.I 5 is a. bottom plan' view of the same. Fig. 6 is a` sectional view,'enlarged, taken on the-line 6--6 in F ig.`4. F ig.m7`is a sectional View, en-

beams 3 and ,4 and a plurality of reinforcing braces 5. The framework is preferably constructed of angle iron in such a manner as to produce a light but rigid and durable frame. Said frame may also be reinforced by lmeans of braces and brace plates wherever desired. The frame is supported upon three'wheels 6 which are mounted for rotation upon brackets 7 of approximate U- shape; the wheels, which are of relatively small diameter, will thus support the frame at the proper elevation. Draft means, such as chains 8, are suitably connected with the front beam of .the frame for the purpose of connecting the same with va tractor whereby the plow is to be drawn over the lield.

The plows, of which any desired number may be used, are connected with the diago- Patented July 29, 1913.

nal rear beam of the frame by specially con- I structed devices including the clevis members C. Each of said clevis members comprises a front plate' 11v having rearwardly extending;ii'anges 12 and 1 3 at its upper and `lower edges and with side walls 14', thus forming a box structure which is open at the-rear. The front plate 11 is provided with slots 15' for the passage of bolts 16, wherebyit is secured upon the frame bar 2in such a manner' as to be capable of sliding sidewise within the limits of the slots 15. lAngle plates 17, which are bolted or otherwise Ysecured upon the frame beam 2 yadjacent to the sides-of the clevis box, are

providedwith setscrews 18 engaging the sidewalls-14,' thus enabling the clevisrbox .to be moved laterally and be held between the set screws '1'8 at any desired adjustment. The top and bottom plates 12, 13 are' pro- Vroo vided with slots 19, 20 wherein a screw bolt 2,1 is guided for lateralmovement,- said screw bolt being'providedl atits upper end witha hea-d 22 constituting a wrench seat and at its lower end with a reduced cylindrical projection 23 extending through and guided in the slot 2O and secured by means of a`washer 24 and a pin 25. One of the side walls 14 extends above'the clevis box to form a flange 26 which is apertured for the passage of an eye bolt 27 engaging the neck of the screw bolt 21, which latter may thus be moved laterally in the .slots'19, 20.y

be hingedly mounted in such a Vmanner as e to be capable of swinging in a vertical plane.v

The sleeve 29 engagingV the screw bolt 21 will enable the plow beam to swing or move in an approximately horizontal plane, the

deviation from the horizontal being equal to` the pitch of the threads uponvthe bolt/21,

such deviation being in practice negligible.

The spring 36 is provided adjacent to its front end with vertically elongated apertures 50, best seen in Fig. 8, for the passage of fastening members, such as bolts 51, whereby said spring is .connected .with one side of the plow beam 33. For the purpose of holding the spring 36 somewhat spaced from the side of. the plow beam, helical springs 52 are coiled about the bolts 51, and said helical.. springs are reinforced by means of a leaf spring 53` whichfis mounted uponthe bolts, said leaf spring having `U-shaped terminals 54 that" are interposed4 between the opposed faces -of the plow beam and'lof the spring 36; The springs 52, .53, while suiiciently powerful to maintain the Sprin j 436 in spaced' relation to the plowbeam wi permit the -said spring todrock slightly .in an approximately vertical plane, owing to.

the presence of the oblong bolt engaging apertures 50. The end of the spring 35 which extends through the slot 34 into the clevis box is provided with slots .38 engaging the bolts 16, thus enabling the spring to be movedwith the clevis box when the position of the latter is changed.

From the foregoing description, it will be` observed that each clevis b ox is laterally adjustable upon the rear beam `of the traction frame, thus enabling initial adjustment tobe made. -A more accurate adjust be eiected without straining the spring,

ment, laterally, ofthe plow beam may be effected by means of the eye bolt 27 carrying the screw bolt 21, and such adjustmentmay composed of rthe liing'edly connected members 35, 36,- owmg to the presence ofthe springs 52,53 interposed between the plow --draft connection to be made.

beam and the spring'member 36, and the l' oblong aperturesin the latter, whereby rocking movement upon the bolts 51 is per- 'mitted By turning the screw bolt 21, the

sleeve 29 may bev adjusted vertically, thus moving the front end of the plow in an upward or downward direction, as may be ldesired, andthus permitting an extremely delicate and accurate adjustment of the This is considered of great importance, especially in a gang plow where it is important that each plow shouldprun perfectly true, a result which may be easily and quickly attained with the construction herein shown and described. In the event of any ob struction being encountered-by any plow, saidplow may yield upwardly or laterally." in either direction, owing to the presence. of the spring vmember lcomposed of thek hingedly connected parts n35 'and 36, the

former of which willi yieldto lateral'pres-v sure in either direction, while the hinge 37 connecting the members 35 and 36 and which is collinear-with thehinge `pin or bolt 32 vwill permit the plow beam to swing in` an upward direction. The obstruction being passed, the spring will restore ,the

plow beam to its imtial position if it has been displaced in a lateral direction, while if it has been displaced upwardly, it

be restored tion.'A

Each upon which a suitably constructed low is lmountedfand carried. IEachdplow eamis provided withl -an upwar extending by gravity to .its initial vposi-,-

plow beam 33 has a standard 38 ,i

bracket 39 which is slightly Ao set in the direction of the landside. Each plowbeam is also provided with a lug 40 which is like-- wise offset in the direction of the landside.

Bolted vupon or otherwise connected with the lug '40 is the lower,l end of a segment rack- 41, the `upper end. of which is connected by a brace 42 with the upper endof the arm 39 by means of a pin'or-bolt 43 upon, whicha lever44 is fulcrumed, said'.Y

lever having a stop member 45 engaging the segment 4rack 41. A-sleeve or bearing .46 secured upon. one side of the plow. beamv serves to `support a shaft 47 carrying at its lower end a gage wheel48, the upper end' -of said shaft being journaledi `in.a collar 49 which is suitablyfconnected with'the' adjusting lever 44, whereby said gagekwheel may beraised or lowered', as 'maybe de'- sired,l tol support the plow the desired position'.

-. In the operation of the 'impbved gang plow it vwill be understood?,that the individual plows are enabled to"'adapted themselves to anyinequalities. in the surface of the ground, and .the improved gang plow may, therefore, be successfully employed for'the purpose of` plowing land which is uneven owing to the presence of bujalo y,wallows and the like. Owing to the special means employed for connecting the` individual plow beams with the traction frame very accurate adjustment of the plows may be made, and the connection is of such a flexible nature that while the low will be maintained for operation in le desired position, no breakage or' injury is liable to result if obstructions are encountered.

Having thus described the invention, what is claimed as new, is

1. In a gang plow, a traction frame, a clevis box connected therewith, a plow beam hingedly associated with the clevis box, and a suitably curved spring comprising two hingedly connected members, one of said members being secured upon the plow beam, and the other member being associated with the clevis box for lateral adjustment relatively to the traction frame.

2. In a` gang plow, a traction frame, a clevis box connected therewith, a plow beam hingedly associated with the clevis box, a curved spring comprising two hingedly connected members, one of which is connected with the clevis box, and means whereby the other of said members is connected with the plow beam for rocking movement with reference thereto; l

3..'111 a gang plow, a traction frame, a clevis boxconnected therewith, a plow beam a plow beam hinge hingedly associated 'with the clevis box and a suitably curved spring comprising two hingedly connected' members, one o said 'members being connected with the clevis box, and means ywhereby the other of said members is connected with the plow beam for rocking movementwith reference thereto, said means including springs whereby said member is supported 1n spaced relation to the plow beam.

4L. In a gang plow, aA traction frame, a clevis box adjustabl connected therewith, (ily associated with-the clevis box a suitably curved spring comprising two hin edly connected members, one of said mem rs being connected with the clevis box for adjustment therewith, and means whereby the other member of the curved spring is connected with the plow beam for rocking movement with reference thereto, said means including connecting bolts and springs upon said bolts between the opposed faces -of the plow beam andthe spring member; the latter being provided Ilwith oblong apertures for the passage of the connectin bolts.

In testimony whereof I aiiix my signature in presence 'of two witnesses.
